Captions, lock the layer so we don't move it unintentionally
If you drag the in or out point of a caption on the captions layer sometimes you can accidentally move the entire layer along the time line. If we could lock the layer but still be able to edit and add captions this would prevent this issue from happening. Currently if you lock the layer you can not edit it, just as you want the lock to work for any other layer.

Thanks, we will keep this mind for future versions. I suggest increasing the height of the caption track.
This is especially important given that you cannot move multiple captions without cutting. I accidentally moved the caption layer then continued adding captions before realising my mistake, so now a large number of them are out of sync. I'm editing a feature-length film so this is somewhat of an issue.
